Optimal transportation and barycenter problems via convex functions
This work surveys developments in optimal transportation. The first three chapters develop background to optimal transportation problems and the associatedWasserstein distances in increasing levels of specificity. The first chapter introduces optimal transport problems and known properties …

Managing pavement in a busy urban highway network
In this dissertation, two dynamic transportation models are formulated and analyzed. When employed in optimal control exercises, these models determine for some metropolitan highway a set of optimal transportation policies, specifically relating to the problem of pavement management. The first …

Scenario discovery for a future of automated mobility on-demand in the urban environment
… has always been a hindrance in the field of transportation planning. It is difficult to make robust decisions regarding optimal transportation policies when uncertainty is so wide. This project presents a novel approach for applying scenario discovery to agentbased simulation. In scenario …

Analysis of a hospital network transportation system with discrete event simulation
VA New England Healthcare System (VISN1) provides transportation to veterans between eight medical centers and over 35 Community Based Outpatient Clinics across New England. Due to high variation in its geographic area, it has been a continuous challenge for VISN1 to develop an optimal …

Optimizing construction and utilization of wheat storage facilities to minimize post-harvest losses
The use of inefficient wheat storage and transportation facilities in developing countries often causes significant quantity and quality losses. These post-harvest losses are estimated to be as much as 20% of harvested wheat and a study by the Government of India puts the total preventable wheat …

Design and analysis of particle-based algorithms for nonlinear filtering and sampling
… a unique control law for FPF. In Chapter 3, the optimality criteria from optimal transportation theory is used to identify a unique control law for FPF, in the linear Gaussian setting. Two approaches are outlined. The first approach is based on a time-stepping optimization procedure. We consider …

Feedback particle filter and its applications
… diffusions with continuous observations: 1) The optimal control solution is exact: The two posteriors match exactly, provided they are initialized with identical priors. 2) The optimal filter admits an innovation error-based gain feedback structure. 3) The optimal feedback gain is obtained via a …
